THOMAS MARONEY, OF BUFFALO, NE\V YORK.

CAR-REPLACER.

SPECIFICATION forming part of Letters Patent N0. 607,256, dated July 12,1898. Application filed February 2, 1897. Serial No. 621,638. (Nomodel.)

To all whom it muy concern:

Be it known that I, THOMAS MARONEY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain'new and useful Improvements in Oar-Replacers; and I do,

which will be permitted to move under the.

influence of contraction and expansion due to exposure and inclementweather and thereby eliminate strain upon the rails orwarping,twisting,or other deran gement, and which will cause a derailedcar to be readily replaced upon the rails with facility and with aneconomical expenditure of power. Y

To the accomplishment of these and other objects my invention consistsin providing a car-replacer or wrecking-frog having a longitudinal curveand a variously laterally inclined bearing-surface with securingmechanism designed to permit slight independent movement of the frogwith respect to the rail.

Referring to the figures on the drawings, Figure I isa top plan View ofa section of railway-track providedwith my frogs. Fig. 2 is a sideelevation of the subject-matter of Fig. l. Fig. 3 is a similar View ofthe opposite side. Fig. 4 is an end elevation of the frogs applied tothe rails. Fig. 5 is a transverse section on the line 4 4, Fig. 1. Fig.G is a perspective View of the inside frog. Fig.y 7 is a similar view ofthe outside frog. Y Sis a bottom plan View of the inside frog, and Fig.9 is a similar view of the outside frog.

Referring to the numerals on the drawings, l and 2 indicate the insideand outside rails of a section of-track, so called for the reason thatthrough them respectively are secured an inside wrecking-frog 3 and anoutside wrecking-frog 4, located, respectively, between the tracks andupon the outer side of the outside rail. The inside frog 3 is cast insteel or other suitable hard metal lin the Fia.,

form illustrated in the drawings, having a .preferably rectangular liatbase 5, front and rear walls G and 7 perpendicular and inwardlyinclined, respectively, and having their upper 'edges S and 9 upwardlyinclined in different degrees toward the center, at which point theinclines are connected by a medial surface curved longitudinally indifferent degrees at the back and front to produce a bearing-surfaceupon the top of the frog, which will be upwardly inclined from theopposite ends of the frogs and will cause a graduallyincreasing lateralinclination to a point at the middle of the frog, where the greatestlateral inclination occurs, the upper edge of the frontwall or the frontedge of the bearing-surface being rounded in gradually-decreasing degreefrom the center of the frog toward its` ends.

l0 indicates a flange projecting upwardly at the rear of thebearing-surface and gradually widening from a point at a suitabledistance from the ends of the frog to the frogcenter, where they mergein the laterally-inclined portion of the surface, permitting an unbrokenincline from the rear edge of the frog-center to the rounded edge at thetop of the front wall.

The' frogs are preferably cast hollow, as illustrated, and are providedupon their bottom surfaces with teeth or projections designed to securesaid frogs to the tie's Il of the road-bed. l

In so far as the preceding description is concerned both the inside andoutside wreckingfrogs are formed alike, with the exception that thehighest point of the front wall of the outside frog vis not necessarilyrounded, as described, and I shall now proceed to a description oftheinside-frog-securing mechanism, which differs from the outside-frogmechanism in the manner of arrangement, though not in the generalconstruction.

l2 indicates a lateral projection extending from the front wall G of theinside frog immediately below the rounded edge, provided with anincline-sided recess 13, designed to constitute the way for avertically-movable inclinesided slide I4, constituting one side of arectangular securing-hook 15,`designed to be hung over the rail for thepurpose of securing the frog thereto.- Any suitable means may be'provided for slidingly secur- IOO ing the slide 14; within its way; butI prefer to employ a screw 16, passed through the wall of the frog fromits interior and provided with a squared extremity 17, designed toproject into a slot 1S in the slide 14. It will be observed that bymeans of this arrangement of the securing mechanism the rail and frogmay move relatively under the influence of cold and heat, as the metalof the rail and frog expand or contract diiferently under the sameconditions, or the frog may be adjusted to rails of various heights, theupper corners of the securing-hooks of each frog being preferablyrounded, as illustrated, for a purpose to be made apparent. Theconstruction of the outside frog is identical, as before remarked, withthe construction of the inside frog, except that an incline-sided recessor way 19 is provided in the front wall of the outside frog instead ofin a projection, as in the case of the inside frog, and the face of theslide 14: is substantially iiush with the face of the frog, thesecuring-hook and its connection being identical with that described.

In use my device is employed as follows: Supposing the car to have beenderailed, the frogs are placed in the position indicated in thedrawings, being located, respectively, adjacent to the inside of onerail and the outside of the other, and the securing-lugs are driven intothe ties by the weight of a passing vehicle, the securing-hooks beinghung over the rails to prevent lateral displacement. The car is thenpropelled toward the frogs until the flanges of the wheels ride upon theincline of the bearing-surfaces. As the flanges progress upon theincline they meet the lateral inclination and gravitate toward the frontedges of the frogs. By reason of the projection 12 between the insidefrog and the track the iiange of the wheel traveling over the surface ofthe inside frog will gravitate over the rounded portion of the frontWall of said frog and will be supported upon the projection before theflange of the opposite wheel has reached the front edge of the outsidefrog, and will thus be brought to a level with the top of the rail.Continued movement of the car will now cause the flange to gravitatefrom the end of thevprojection and between the rail and the frog, and atthe same time the flange of the opposite wheel will glide over thesecuring-hook of the outside frog and readily drop inside the rail at orabout the same time that the fiange of the other Wheel drops beyond theprojection 12 of the inside frog. The front wheels of the truck will inthis manner be replaced upon the tracks and the rear wheels will bereplaced in a similar manner as the vehicle progresses, the flangesprojecting from the rear edges of the frogs serving to guide the flangesof the wheels when they come in contact therewith.

While I have illustrated and described what appears to be a preferableform of my invention, I do not desire to limit myself to the details ofconstruction herein shown and described, as it is obvious that thevarious inclines and curvatures of the surfaces of the frogs might bevaried in degree as experience may dictate.

1. A frog, provided with a lateral projec' tion or offset adapt-ed tobear against the side edge of the rail, and having mounted therein avertically-adjustable securing-hook.

2. A frog, having a lateral projection or offset thereon, adapted tobear against the side of the rail, and provided with a grooveconstitutin g a guideway, and a securing-hook whose vertical portion isadapted to fit and move within said guideway.

3. A frog, provided with a lateral projection or offset, adapted to bearagainst the rail, the said offset having a vertical dovetailed groove orrecess therein, a laterally-projecting pin located Within said recess,and a securing-hook whose vertical portion is adapted to fit and movewithin said dovetailed groove or recess, and is provided with anelongated slot for the reception of said pin.

4. The combination with a frog provided with an incline-sided recess, ofa securinghook provided with a slot and incline-sided slide, and a screwdesigned to pierce one wall of the frog and provided with a squaredextremity engaging the slot in the slide, substantially as specified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
